# Activate

<Tip>
  You only need to use this endpoint if you have device **activations** enabled on the license key benefit. You then use this endpoint to reserve an allocation for a specific device. Storing the unique activation ID from the response on the device and using it as extra validation in the [/validate](/api-reference/customer-portal/license-keys/validate) endpoint.

  Not using **activations**? Just use the [/validate](/api-reference/customer-portal/license-keys/validate) endpoint directly instead.
